About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-50S
The AirTAC SAIJ160X90-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 40 to 90 mm from its 90 mm nominal stroke. It delivers a robust 10053 N pull force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. The extruded aluminum barrel integrates dual sensor grooves, and this -S variant includes a magnet for direct switching via AirTAC CMSE reed or DMSE electronic sensors.
This model features a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread for a tight, reliable pneumatic connection. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning; it does not lock the load without live air. For load-holding requirements without continuous pressure, an external pilot-operated check valve or a related SAIL pneumatic lock cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-50S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within a 40-90 mm window during machine commissioning, eliminating the need for external mechanical stops or custom spacer rings.
Product Size Changeover
Quickly adapt a heavy-duty packaging line to different carton sizes by adjusting the rear stopper screw up to 50 mm, minimizing downtime between production runs.
Heavy-Duty Positioning
Leverage the 10053 N pull force to shift heavy pallets or fixtures into place, relying on the stainless steel rod for durability in harsh industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-50S the Right Cylinder?
Choose this 160 mm bore when an application demands high thrust, such as the 10053 N pull force at 0.5 MPa, alongside precise end-position tuning without swapping cylinders. If the 50 mm adjustment range is excessive for your machine layout, stepping down to a smaller adjustment code or a fixed-stroke SAI cylinder simplifies the setup. The generous 50 mm retract window is ideal for product changeovers on a line, allowing operators to dial in the exact stroke needed for varying package sizes.
As a dimensionally interchangeable ISO 15552 cylinder, replacement requires matching the 160 mm bore, 90 mm stroke, 50 mm adjustment, PT port, and -S magnet. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the 90 mm stroke is short, side-load stress is minimal, but the substantial 40 mm rod diameter still handles high bending loads effectively without needing an external guide.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-50S FAQ
At a 0.5 MPa operating pressure, this 160 mm bore cylinder generates a push force of 10053 N and a pull force of 9425 N. It can deliver up to 2050 kgf at its maximum 1.0 MPa pressure.
The rear adjuster screw lets you mechanically shorten the 90 mm nominal stroke by up to 50 mm, providing an adjustable travel window of 40 to 90 mm. This stopper only sets the end position; it does not lock the load without live air pressure.
